## Release v0.51.259 — Release IA (stage-r7)
Two ship-ready @rodboev bug-fixes from today (the clean subset of the prioritized 6).
### Fixed
| Issue | Fix |
|-------|-----|
| #3582 | **Edge-TTS playback no longer has a ~31s delay / playback error** — `_handle_tts` streamed audio without `Content-Length` on an HTTP/1.0 server; audio is now buffered and sent with an exact `Content-Length`. |
| #3583 | **CLI-bridge message reconstruction strips orphaned `tool_calls`** (assistant `tool_calls` with no matching `tool` response, left by an aborted bridge) so the next request no longer 400s on strict providers. |
### Held back from the 6-PR batch (Codex regression gate caught a real defect in each)
- **#3586/#3603** (`is_cli_session_row` reclassification) — CORE: messaging rows become non-CLI, but the sidebar open path only imports when `is_cli_session`, so opening a Discord/Telegram session shows a transient stub and the next send 404s on `/api/chat/start`. Needs a client import-gate fix + live verify. **Held.**
- **#3585/#3604** (cron-overflow) — removing `exclude_sources=None` also re-excludes `source='webui'` rows, dropping sidecarless WebUI session recovery from `/api/sessions`. Needs a separate webui recovery pass. **Held.**
- **#3587** (intermediate reasoning) — `on_interim_assistant` is suppressed upstream for contentless tool-call assistant messages (`run_agent.py:3834`), so advancing the reasoning index there never fires at tool-call boundaries → mis-attribution. **Held.**
- **#3538** (self-update stash-pop) — BRICK data-loss (`git reset --merge` + `git stash drop` discards user mods), still unaddressed. **Held.**
### Gate
- Full pytest suite: **7645 passed, 0 failed**
- ruff: CLEAN
- Codex (regression): 3 rounds — 4 PRs dropped/held for real regressions → **SAFE TO SHIP** on the clean 2
